Adam that is all great information, thank you. However, the policy is
clear: commit resources for integration testing, or it needs to move
out of tree.

It's not a mountain of resources. Just an integration test that passes
reliably, and a couple of QPID+OpenStack experts who we can contact when
it breaks. If nobody is willing to put that much effort in, then it is
not really something we want in our official messaging library tree.

So please if you can carry that message up to those who want it to stay in
tree, that would be helpful and would put the stops on this deprecation.
